CONDUTT-TURNING MJAGEZNE.

Application filed. June 9, 1926. Serial No. 114,718.

This invention relates to conduit conveying'and turning mechanism and especially to a machine for receiving conduits or tiles in a vertical position as they are formed from plastic material by being extruded through a die and conveying and depositing the same upon a platform in a horizontal position. It is the primary object of my invention to produce an improved machine for performin this function. g

riefiy, my invention embodies a conduit receiving carrier and power means for reciprocally moving the carrier to and between a conveyor and platform. The carrier when adjacent the conveyor is adapted to receive a conduit in the upright position from the conveyor and cooperating'means is provided for tipping the carrier as the same is moved toward the platform whereby the conduit will be deposited thereon in a horizontal position. Further means is provided for preventing movement of the conduit from the platform when the carrier returns therefrom. It is a futher object of my invention to provide an improved mechanism of this type.

In the accompanying drawings I have illustrated certain specific embodiments of my invention, but it will be understood that the invention can be otherwise embodied and that the drawings are not to be construed as defining or limiting the scope of the invention, the claims appended to the specification being relied upon for that purpose.

Referring to thefigures of the drawing:

Fig. 1 is aside elevation .of my improved machine.

Fig. .2 is a like view thereof showing the carrierin another position.

Fig. 3 is a sectional view taken on line Illa-III of'Fig. 2.

Fig. 4: isa-plan view'of the machine. lln the drawings, 1 indicates the barrel or cylinder from which plastic material is forced through a die 2 to form a tile 3. The tile is received on a board 4, resting on a vertically movable plunger 5 and the tiling is cutoff by a wire 6 when the tile has been extruded the proper length. The plunger 5 is adapted to move downwardly between the rolls of the conveyorl', the board 4 being of a width to rest on the rolls of the conveyor. Beneath and extending downwardly from the conveyor 7 is a long gravity conveyor 8 111g machine. p

A. carrier 9 is provided for receiving the tile from the conveyor 8 and depositing the same in a horizontal position on a platform 10. This platform rests on rollers 11 where by the platform can be adjusted along to receive several tiles thereon. When the platform is fully loaded, a crane 12 carries the same to the stacking and drying part of'the works.

:One end of the carrier is provided with rollers 13for receiving the'tile on itsboard 4 and, when the carrier is in its vertical position at the end of the'conveyor 8, these rollers 13 are slightly below the conveyor rollers whereby the tile rides into the carrier by gravity. In its horizontal position, the carrier is supported on tracks 1d b rollers 15 on metalstraps. 16 riveted to the carrier.

The carrier is reciprocated to and between the conveyor 8 and platform 10 by a motor 17 throughthc following mechanism. The motor drives a shaft 18 through a belt 19, a hand wheel 20 being provided on the shaft for manually adjusting the same. A worm 21 on the shaft 18 drives a .worm wheel 22 on a shaft 23. A crank 24 on this shaft is connected by a connecting rod 25 to a cross head 26 slidable .on tracks 27. Straps 28 rigid with the cross head, have their lower ends slotted at 29, which slots engage over trunnions '30 .on the carrier.

The motor 17 operates continuously and the cross head is slowly moved reciprocally to and between the conveyor 8 and platform 10. The crank arrangement causes a slight pause of the carrier at :each endof its move ment. During this pause at the conveyor 8 (Fig. 1), a tile 3 is guided into the carrier. Return movement of the cross head pushesthe carrier to the right at the trunnions 30 the carrier thereupon engaging against and tipping to the right about a roller 31. During this movement the lower rollers 15 are guided along straps 32 onto the tracks 14.. Continued movement of the cross head to the right brings the carrier and its tile to a position over the platform 10.

Then thecar'rier moves again to the left, the tile must be left deposited on the platform. A lever 33 'is pivoted at 34 and a downwardly projecting end 35 thereof is extending to the tile receiving and conveyadapted to engage and hold the tile from returning with the carrier. The lever is automatically tilted in both directions about its pivot by mechanism now to be described. eights in the form of rollers 36 provided on the lever for aiding in its movement, these weights being confined to the lever by the crooks 3'7 at the lever ends. At the end of the left hand movement of the carrier, rollers 38 on the sides thereof engage against abut-merits 39, whereby the carrier is tipped to its vertical tile receiving position.

In Fig. 2, the end 35 of the lever is illustrated as engaging behind the board 4 of the tile in the carrier, the weights 36 holding the same in place. When the carrier moves to the left, the tile will be held from movement therewith. Just before the carrier reaches the position shown in Fig. 1, the free end of an arm 40 carried by the shaft 23 engages against the right hand end of the lever 33 and tips the lever to the position shown in Fig. 1, whereupon the weights 36 roll to the right hand end of the lever. This movement is limited by a stop 41.

Upon movement of the carrier to the ri ht, a plate 42 carried by the cross head 26 engages against a lever 43 pivoted at 44 and moves such lever to the right against the action of a spring 45. Another arm 46 of lever 43 is connected by a link 47 to an arm 48 pivoted at 49. An arm 50 has one end pivoted at 49 and its free end engaging beneath the right hand end of lever 3". An arm 51 is connected rigidly to the arm 48 and is connected to the arm 50 by a spring 52. Through this connection, the lever is pivoted to the left upon movement of the cross head to the right. It will be noted that both ends of-the link 47 are adjustably connected to the arms 46 and 48.

lVhen the lever 33 is pivoted to the left, the weights 36 roll to the left hand end of the lever. To prevent the left end 35 from engaging and marring the tile, I provide a lug 53 on the lever and a cooperating plate 5'4 on the carrier. The lug engages the plate and sustains the weight of the lever until the carrier has reached a position wherein the end 35 will drop back of the board 4.

It is believed that the construct-ion and operation of my machine will be clear without further description herein. The ma chine operates continuously and automatically, the crank arrangement providing suiiicient pause at each end of the travel of the carrier to permit the loading and unloading thereof.

Having thus described my invention, what I claim is:
